I have a small indentation, like a tiny crevasse, on the front, right side of my forehead. About as long as my pinky. Not too deep, but enough to notice it when touched. You can even see it. I asked my neurologist about it, and he said it had something to do with the forming of my skull, when I was a baby. Problem is, I ve been shaving my head for close to 15 years. I told him this is something that wasn t there before! He said it was nothing. Sigh.. I know how my head looks, I shave it three times a month. I ve been seeing my neurologist for constant headaches for almost three years. Had an MRI about a year ago. Everything was good. He just keeps putting me on anti depressants. Anyway, ever heard of this problem?
